Description

一种白合金冷拉拔加工润滑剂的组合物
技术领域
本发明属于金属加工润滑剂领域，特别涉及一种白合金冷拉拔加工润滑剂的组合物。
背景技术
白合金由美国人巴比特发明而得名，因其现白色，又成为巴氏合金。包括锡基轴承合金和铅基轴承合金，被广泛应用。它具有减摩特性，是唯一适合相对于低硬度轴转动的材料，与其它轴承材料相比，具有更好的适应性和压入性，广泛用于大型船用柴油机、涡轮机、交流发电机，以及其它矿山机械和大型旋转机械等。其主要合金成分是锡、铅、锑、铜。锑、铜，用以提高合金强度和硬度。
巴氏合金的组织特点是在软相基体上均匀分布着硬相质点，软相基体使合金具有非常好的嵌藏性、顺应性和抗咬合性，并在磨合后，软基体内凹，硬质点外凸，使滑动面之间形成微小间隙，成为贮油空间和润滑油通道，利于减摩；上凸的硬质点起支承作用，有利于承载。
根据国标：巴氏合金分锡基和铅基合金两种。铅基合金的强度和硬度比锡基合金低，耐蚀性也差。因此，通常在使用巴氏合金的时候，通常选用锡基合金。铅基合金使用比较经济。
金属拉拔是一种古老的加工方法，用途广泛，简单适用。它是通过模具孔减少加工材料的截面，获得高精度、高光泽度的管材和棒(丝)材的一种塑性加工工艺。拉拔通常是冷加工过程，是一种连续和稳定的工艺。由于拉拔过程中的摩擦热和模具磨损以及工件的表面质量要求，需要使用拉拔润滑剂进行润滑和冷却。拉拔润滑剂可降低拉拔应力和能耗，减少模具拉裂和保持较低的拉拔温度。选择适当的润滑剂，能保持拉拔过程的润滑膜对产品的表面光洁度有很大的影响。
对金属坯料施以拉力，使之通过模孔以获得与模孔截面尺寸相同的制品的塑性加工方法称为拉拔。大量的棒材、丝材和管材是采用拉拔工艺生产的，而摩擦在拉拔工艺中起着关键性的作用。选择相应的润滑剂是根据摩擦特性和冷却能力。流体润滑是拉拔中最为理想的润滑状态，能大大降低摩擦系数和摩擦表面温度，不发生磨损和粘结损伤，提高模具寿命和制品的表面质量。润滑剂要求具有良好的粘附性、耐温性、耐压性、能形成稳定的润滑膜，起到润滑和冷却的作用，拉拔后润滑膜易于清除，减少动力消耗，改善加工金属表面的质量和公差，提高光洁度。
